INVENTOR .ITarfiq LlSiBWiD 7 BY momma MART-I. .L IISICWICZ, OF NE'WARK,NEW JERSEY.

To all whom it may concern:

Be it known that I, MARTIN Lisiowloz, a citizen of the United ,States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in DemountableMechanically-Resilient Tires; and I do hereby declare the following tobe a full, clear, and exact description of the .invention, such as willenable others skilled int-he art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and tocharacters of refernce marked thereon, which form a part of thisspecification.

he present invention relates to improvements in tires for vehicles; andthe invention has reference, more particularly, to a novel constructionof resilient mechanism adapted to be inclosed in an outer shoe ofrubber, or other similar material, and which .isdesigned to take theplace of the inner tubeof a pneumatic tire, so asto provide an easyriding shock-absorbing tire, having the appearance of the ordinarypneumatic tire commonly used, yet not being readily liable "to deflationby punctures as are such pneumatic tires. l The invention, therefore,has for its principal'objei'zt' to provide'a mechanically resilient tireconstruction; and the invention has for a further object the provisionof a mechanically resilient tire construction embodying features ofconstruction which renders the same readily demountable from the fellyand rimof the wheel.

Other objects ofthe present invention,

not at this time more particularly enumerated, will be clearlyunderstoodfrom the following detail description of the same.

With the various objects of my present invention in v1ew,.the sameconsists, primarily, in the novel construction of demountablemechanically resilient ,tire for automobiles and othervehicles'hereinafter set forth; and the invention consists, furthermore,in the novel arrangements and.

combinations of the several devices. and parts, as well as in thedetails'of the construction of thelsame, all of which will be more fullydescribed in the'followingspecification, and then finally embodied inthe claims appended thereto.

The invention is clearly illustrated in the accompanying drawings, inwh1ch:-,-

wheel equipped with my novel construction of demountable mechanicallyresilient tire a portion of the wheel felly and tire structure beingshown in vertical section, to illustrate the inner construction thereof.

Fig. 2 is a detail transverse sectiomdrawn on an enlarged scale, saidsection being ployed in all of the hereinabove described views, toindicate corresponding parts.

Referrin now to the said drawings, the

reference 0 aracter 1 indicates the hub of the vehicle wheel, from whichradiate the usual spokes 2, which terminate in the folly 3. sec ired uon said felly 3 in any suitable manner, pre erably, by shrinking. on thesame, is a fixed metallic rim member at Projecting from the exteriorsurface of said rim member 4, and spaced at regular intervals aroundthecircumference thereof, are

bosses or projections 5, each having, at one end, a female portion orreceivingsocket 6.

The reference character 7 indicates a demountable rim. Projecting'fromthe surface of said demountable rim 7, and spaced at regular intervalsaround its inner circumference, are bosses or projections 8, eachhaving, at one end, a male portion ortongue able rim 7 are outwardlyinclined annular 9. Integrally formed in connection with the outer sidemarginal edges of said demount-.-

seating fiangeslO, the purposes of which will presently appear. a

' Provided in said demountable rim 7 and preferably formed in thatportion thereof where the body of the rim is thickened by the bosses orprojections 8, are internally threaded openings 11. Secured into eachopening 11 1s an'exteriorly threaded shankportion 12, from the free endof which projects an anchor-stud 13 of reduced diameter.

- The reference character 14 indicates a shoe-supporting ring, which isspaced concentrically away from said demountable rim 7. Saidshoe-supporting ring 14' is pro-' vided at its marginal ed es withvertical flange portions, the inward y extending porversely,

,-'-of said demountable rim 7."

tion 15 of eachvflange extending beyond the interior side of said ring14, and the outwardly extending portion 16 of each flange extendingbeyond the exterior side of said ring 14. 1 v Arrangedwithin theannular'space intervening between the said demountable rim 7 and saidshoe-supporting ring 14 are a series of arcuate spring-members 17. Oneend of each spring-membervl'i is provided with an eye 18, and theopposite end thereof with a bifurcated, portion providing a longi--tudinal slot 19. aid spring-members 17 are secured in operativepositions relative to the said demountable rim 7 and said shoesupportingring 14 by engaging the eyes 18 thereof over the anchor-studs l3, andthen engaging next adjacent anchor-stud 13, so' that said slotted endoverlaps the anchored end ofthe spring-member which is secured by itseye 18 over said next adjacent anchor-stud 13. As thus 'disposed saidspring-members extend from anchor-stud to anchor-stud, and archoutwardly so that their main body portions contact or engagetangentially-the surface of said shoe-supporting ring 14. The

contacting portion of each spring-member,

as it thus engages said shoe-supporting ring, is disposed between saidinwardly extending portions'15 of the-vertical flanges of the latter,and are held thereby against undue lateral play, 'or displacement fromsuch proper relation to said shoe-supporting ring 14. If. desired, saidshoe-supporting ring 14 may be transversely bowed, as at 20, to reducethe frictional contact of said spring members l7 therewith. In order toprevent creeping of said shoe-supporting ring 14 around the wheel, thesame is provided with a pair of receiving sockets 21, diametricallyopposite each other, and a pair of diametrically opposed anchor-studs 13are elongated, to provide extension portions 13' receivable in saidreceiving-sockets 21, thus serving to retain said shoe-supportingringcircumferentlal I against longitudinal or movement. I

The reference character 22 indicates a tire-tread or outer shoe, theinner surface of whichis preferably formed to provide a rib 23receivableybetween the outwardly extending portions '16 of the verticalflanges of said shoe-supporting ring 14, thus holding said shoe 22against lateral dlsplacement.

The side portionsf24 of said shoe 22 extend inwardl -enigma side oftheannular space between the demountable. rim 7 and said shoe-supportingring 14, and thus inclose the spring-members 17. The marginal edges 25of said side-portions 24 are registered over said annular fse'atinflanges 10 said demountable rim is pierced transat suitable intervals,for the pasthe'slotted ends thereof over the through said perforate"able-rim 7 to which it retractive circumferential movement tend-,,

he body of" sage of retaining bolts 26. Exterior clamprings 27 areoverlaid upon thesa'id marginal edgest25 of said shoe 22, the same alsobeand thus hold the shoe in place.

The shoe and the interior mechanism of the tire may all be assembledandproperly' mounted upon the demountable rim 7, while the latter isremoved from the wheel. Hence, an extra or spare tire,'embo'dyingmynovel construction, may be be applied to the'whe'el aflixed thereto getsout of dentally damaged. When in case the tire order, or is acciit isdesired to place a tire on the wheel, the bosses 8 of the demountablerim 7 are registered with the spaces between the bosses 5 of the fixedcarried all ready to rim member 4 of the wheel, and then the demountablerim 7 is pushed transversely over said fixed rim-member 4. After beingthus positioned, the demountable rim -7 is' moved longitudinally ;.orcircumferentially upon said fixed rim-member 4 to carrythe male portionsor tongues 9 of into interlocking relation with the female portions orreceiving sockets 6 of the bosses 5, thus locking the demountable rim 7against lateral displacement rim-member 4. In order to hold'the. partsin such interlocked relation, one of said cl'amp-rings-27 is providedwith one or more extend ng perforated ears 28,

lnwardly from the fixed the bosses 8 which extend inwardly over one sideof the felly 30f the Wheel. Secured tosaid felly 3 by its bolt-portion29 is a pivot-member 30, upon which is pivoted-by its ear 31 ascrew-threaded shank 32 havlng a'shoulder 33 at its inner end. Thisshank 32 is passed ear 28, until the latter abuts againstvthe shoulder33, and then a lock-nut 34 is screwed upon the free end of said shank,which rojects from the oppositeside of said per prate-ear 28, thusanchoring said ear'28- to thefelly 3, and thereby holding saidclamp-ring and demountthat the present inven-.

is bolted against any tion provides a very 'simplyconstructed, yet ihightly eflicient mechanical tire, the arcuate spring-members of whichabsorb the shocks of traction. The shoe 22 giving the, tire theappearance of the ordinary pneumatic tire, and the demountable rimconstruction provides all-the convenient features inherent in the readyto use tire. p

I am aware that some changes may be ade; in the-several arrangements andcomdetails of the construction of the same,

without departing from'thescope of my invention as defined in theappended claim.

Hence, I do not "limit my invention to the exact arrangements andcombinations of the various parts as described in'the foregoingspecification, nor do I confine myself to the exact details of theconstruction of said parts as shownin the accompanying draw ings.

I claim. I Y The combination with the felly of a wheel of afixedrim-member, a demountable rim,

means respectively on said fixed rim-member and said demountable rimadapted when mutually engaged to prevent lateral displacement of thelatterfrom the former, a

detachable annular member atone side of said demountable rim, fasteningbolts ex tending through said demountable rim and, I

said annular member, an inwardly extending perforate ear integrallyconnected with said-annular member and adapted to extend over the outerside of said felly, a bolt pivoted .to the outer side of said felly soas to swing in a plane parallel to theface of the Wheel, a shoulder onsaid bolt adjacent its.

pivoted end, said perforate ear being adapt ed to slip over the free endof said --bolt so as to abut against said shoulder, and a nut engaged onsaid bolt on the opposite sidelof said perforate ear. In testimony thatI claiinthe invention set forth above I have hereunto set my hand this30th day of December, 1916. j MARTIN LISIOWICZ. Witnesses: Q GEORGE D.RICHARDS, FREDK H. W.. FRAENTZEL.
